SPECIFICATION forming part of Letters Patent No. 255,856, dated April 4,1882,

Application filed December 23, 1881. (Model.)

`l'o all whom it may concern:

Be it known that I, G. RAYMOND HEIZMANN, of Reading, Pennsylvania, haveinvented a new and useful Improvement in Machines for Paring, Ooring,and Slicing or Dividing Apples, of which improvement the following is aspecification. I

The machine herein described belongs to the class of apple-parers inwhich the apple-bearrio ing shaft is susceptible of certain freelongiasmall portioiLof the upper part of the frame being broken away to exposethe recess u, traversed by the lug t of the supporting-bar t; Fig. 2, aplan of the machine, Fig. 3, a sectional elevation of the same on theline o o of Fig. 1;'Fig. 4, a sectional elevation on the line Izo zo ofFig. l. The other views represent details, Fig. 5 being a side elevationof the trackbar lo, and Fig.V Ga sectional elevation of the same on theline m of Fig. 5; Fig. 7, a side elevation ofthe supporting-bar t, andFig. S a front end elevation of the same; Fig. 9, front and sideelevations of the engaging-bolt o, and Fig. 10 a section of the same onthe line zz of Fig. 9; Fig. 11, side and front elevations ofthetrack-bar la, with a supplementary paring-4 knife rigidly attached toits front end. ac a2 is the frame, the top part, a2, of which 4o-ishollow or chambered, as indicated in Figs.

1 and 4. y

b is the paring-knife, which is adjustably secured, as by a screw, tothe ordinary upright trough-shaped standard, o, which has a rotaryvibration on a vertical shaft, (not shown,) by which it is attached tothe cross arm or stop d of the horizontal shaft d, the latter beingsurrounded and `controlled by a spiral spring, e, all constructed andarranged in a well-known 5o form and manner.

curved in a plane at right angles to its length,

as shown at 7c in Figs. 5 and 6. A track, l, is formed in relief on eachside of bar 7c by cutting away a part of the thickness of the bar,

forming notches or depressions m and 'a at 65 j either end of saidtracks. The tracks l are beveled at their front ends, as shown in Figs.l and 5. The rear end ot' the track-bar k comes in contact with thecrank y.

o, Figs. l, 2, 3, 9, and 10, is a bolt cored out 7o from top to bottom,as shown in Fig. 9. It is vloosely held in an upright position againstthe dat face of the upright part c ofthe frame by means of an ordinaryundercut stud, p, which projects from the face of the frame, and permitssaid bolt o to slide freely up and down thereon. The lugs r and rproject from the broad front face of the bolt o, as shown in Figs.

l, 3, and 9. '.lhembolt o is provided with projections s and s', Fig. 9,which are shortseg--So ments of screw-threads that in the operation ot'the machine are caused to engage the thread of the shaftf.

t, Figs. l, 3, 4, 7, and S, is a bar located underneath the track-bar7o. It slides through 85 the chamber in the head a2 of the frarre. Ithas a lug, t', which is brought into contact with the front and rearwalls of the` recess fu. of said chamber, (see Fig. 1,) and thus limitsthe movements of the said har t. The bar t 9o has at its fore endthelugs t2, which are brought into contact with 'the under and rearsurfaces of the lugs r and r of bolt o, and serve to hold said bolto upand keep said bar t from moving forward prematurely at certain periodsin the operation of the machine, as below described.

bz, Fig. 1, is an ordinary coring and `slicing knife, by which theapples are sliced crosswise. Another device (shown in Figs. and 2)conroc sists of the tube L3 for coring the apples and the radial bladesb4 for dividing them lengthwise. The web b5, cast or otherwise formedintegral with the radial arms b4, serves as a base to an upright arm, b,upon which the coring and slicing knife Wis adjustably attached,

the whole forming one reversible piece,which is capable of adjustment,as desired, to slice the apples crosswise or divide them lengthwise, andwhich, after adjustment, is held in position on the platform-extensionc2 of the frame by the thumb-screw d2, which works through the slot e2in the side iiange of the platform.

q, Fig. 1l, is the base ot' the supplementary detachable paring-knife Q.q2 is a screw for securing the knife to the base q. g3 is a clearopeningunderneath the knife for the exit of the parings. g4 is a space betweenthe knife q' and the guard Q5. This knife is intended to be used fofparing the rear portion of the apple. After an apple has been put on theforktines t', and before the apple-bearing shaft f has been movedforward, the shaftfis rotated, and the rear part of the apple is thusbrought in cutting contact 'with the edge of the knife q. The machinebeing operated without the supplementary paring-knife, this knife,withits appendages, may be used or dispensed with.

In Fig. l the bolt o is shown to be up, the segments s and s being inengagement with the thread of the shaftf. Vhen the bolt ois down, or, inother words, when the segments s and s are disengaged from the thread ofthe shaft-f, the said bolt o simply bears on the peripheral surface ofthis shaft, which can then be moved back and forth freely through itsbearingsj and j2 without rotation of the shaft.

At the completion of an operation on an apple the shattfis drawn back,the fork-head h, soon after the backward motion of the fork-- shaft hascommenced, striking the shoulder n3, Fig. 5, of the track-bar 7c, andthus carrying back'with it said bar,and this recession of the shaftcontinues until the fork-head h comes against the bolt o,the shoulder n3of the trackbar 7c being then iiush with the face ot' the bolt o, and ifan apple be'then stuck on the fork 4 this act presses back the track-bar7c and the supporting-bar t, causing thc projections s2 and s3 to slideup the inclines n2 of bar k, bringing the said projections s2 and s3about on a level with thc top of the track l and also bringing the lugst2 of bar t under and behind the lugs r and r of the bolt 0. Theprojections s2 and s3 (see Fig. 9) of bolt 0 are now ready to mount thetracks l, and thus bring the screwsegments s and s into position forengaging the screw-thread of shaftf when this shaft is pushed forward.The shaftf, carrying the apple, can now be pushed forward toward theparing-knife without rotation until the thread of-this shaft engages thesegments s and s', from which period until the end of its forwardmovement the shaft fis advancedby turning the crank g.

The lugs t2project upward, and also sidewise, and are employed for twopurposesviz.,tirst,

for supporting the bolt o in the position to which it has been raised bythe sliding of projections s2 and s3 up the inelines n'and, second, forpreventing the bar t from being` prematurely moved forward by frictionof the track-bar k thereon, the said bar t not being intended to bemoved forward until the projections s2 and si have mounted the tracks land raised up bolt 0 sufficiently to free the lugs t2, and thus allowthe supporting-bart to be pushed forward. The lugs t2, by being broughtunder the projections r and r', are caused to hold the bolt o up, andthe contact of these lugs t2 with the rear of the said projections r andr prevents the premature forward movementof the bart.

It will be seen that the track-bar k is pressed forward by the crank,and that when the forkhead 7L has passed the paring-knife b theprojections s2 and sJ have reached the notches m, allowing the bolt 0 todrop,and thus breaking the engagement between the segments s and sandthe shaft-thread. The withdrawal of the shaft f and the otherabove-described operations can then be repeated, and so on indefinitely.

The drawings show the slicing and coring knife b2 in position for use.In such case the coring-tube b3 and radial cutters b4 rest on theplatform o2, as shown in Fig. l. When it is desired to bring thecoring-tube b3 and radial cutters b* into use the thumb screw d2 isloosened, and the combined device is adjusted so as to bring thecoring-tube into horizontal position. In this case the slicing-knife b2lies down on the platform c2.

Instead of employing two tracks, l, one on each face of bar k, as abovedescribed, and

the two corresponding projections s2 and's3,

the two lugs rand r and the twescrew segments s and s', but one of suchtracks l may be used, and in such case only the corresponding one of thetwo projections .s2 and s3 and of lugs l and r and of segments s and sare required. I prefer, however, the form of construction firstdescribed, because it secures lnore freedom of action in theengaging-bolt o.

It will be seen that the track-bar k is employed as the medium foreffecting engagement and disengagement between the thread of theapple-bearing shaft and the counter screwthreads or segments at certainperiods in the longitudinal movements of said shaft. This track-bar isshown to be located underneath the apple-bearing shaft.' It may,however, be located above or on either side of said shaft, the necessarychanges being made in the tracks and in theform ofthat part ofthe framethrough which said bar passes. A

A track-bar located as above described can, with obvious modifications,be employed to advantage in paring-machines which employ a rack, nut,trigger, or equivalent device for carrying screw-threads or segments ofscrewthreads intended'to gear with the thread of the apple-bearing shaftfor the purpose of throwing such screw-threads or segments into or outof engagement with the shaft-threads.
